makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.

Fakeroot-ng runs a program while fooling it into
thinking it is running with root privileges. When
the program does something that only root can do
(e.g. create a device file), fakeroot-ng emulates
the appropriate system calls so that the program
gets a consistent view of its actions. Unlike the
original fakeroot, fakeroot-ng uses the ptrace
interface, which means that it does not suffer some of the limitations that fakeroot does. In particular, fakeroot-ng supports chroot jails.

JExpress is a Java installer builder and auto-updater. It gives you your choice of a standalone installer, including both native and cross platform installers and updaters for Windows, Mac OS X, Linux, and Solaris, or a Java Web Start one-click install. You create your installer quickly with your choice of a simple wizard or a powerful advanced interface, both included. You can bundle the exact JVM you want with your installer. The auto-updater gives you a continuous revenue stream after the sale. Your software is always up-to-date, so your customers have fewer problems. You also get all the features you expect in a top end installer. Your Java application becomes a native program just like any other. On Windows it's an EXE, on Mac OS X an app bundle, etc. If you need something really special, you can customize your installer by adding simple Java classes. You can even get a source license at a reasonable price.

The GNOME NetworkManager is a set of co-operative tools that make networking simple and straightforward. Whether wireless or wired, NetworkManager allows you to quickly move from one network to another: once a network has been configured and joined once, it can be detected and re-joined automatically at a later date. It was designed to auto-detect as much information as possible, seamlessly switches connections when necessary, and provides immediate feedback of the network state to users and applications.

Conary is a distributed software management system
for Linux distributions. It replaces traditional
package management solutions (such as RPM and
dpkg) with one designed to enable loose
collaboration across the Internet. It enables sets
of distributed and loosely connected repositories
to define the components which are installed on a
Linux system. Rather than having a full
distribution come from a single vendor, it allows
administrators and developers to branch a
distribution, keeping the pieces which fit their
environment while grabbing components from other
repositories across the Internet.

DIASER is a cloud storage class combined geo-data replication, long-term archive system, and WAN vault application. Manage long term mixed data archives generated by existing backup software. Ensure availability using commodity hardware. Retain administrative and financial control. It combines a disk-based backup volume management system and triple redundancy with a storage architecture designed to structure months to years of long term sustainable archiving space. It is a quick and low-cost way to make an environment more robust by backing up data in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system. Nodes can be dedicated to storage or used for existing services over unused bandwidth. DIASER works in user space over SSH.

BitNami RubyStack provides a fast, easy way to
develop and deploy Ruby on Rails applications. It
includes Ruby, Subversion, MySQL, SQLite,
ImageMagick, and several Ruby Gems, and will
optionally install Apache 2.2 with rewrite and
proxy support. It supports Windows, Linux, and OS X, so you can share the same Rails environment on multiple platforms.
